maybe desired, and secured in the adjusted v Located forward of'the scraping device, and about midway longitudinally of the frame members 6, is the planing device 22, which includes a body member 23, a knife the movable block 26. The knife is fur thcr secured'inplace by an exterior mem ber27 held in place by a set screw 28 threaded thereinto near its upper extrem=- ity, the inner extremity of .the screw engaging the blade.

about midway thereof is a transversely arranged pin 29 which forms a sort of fulcrum for the plate 27 when the screw 28 is, tightened by forcing it against the knife. The knifeis adjusted in the plane of its 1ocation'by 'means of a screw 30. which is. .journaled in the bodyofthe; plane, its

threaded portion "81 engaging a threaded openingformedin the block 26. .Thescrew is locked against longitudinal movement by means of a collar 32 which engagesthe body of the structure. atthe upper extremity of.

purposes.

The body of the planeis provided on op.-

posite sides: with trunnions 35, which jenter grooves 36 formed in reinforced parts 37 of.

the frame members 6. The portions'of the members .6 in'front and rearof the parts 37 are relatively thin. Theparts 37 are made of considerable thickness,-however, in"-or .der to give the necessary width to the: grooves and also close these grooves onthe outside, whereby the trunnions of the plane are:- sealed. These grooves are closed at their. rear extremities. The rear portions of the. grooves are also lowermost, and when the trunnions engage these rear po'rtions the plane is in position'for' use :(see Fig. 3). grooves the latterextend upwardly and forwardly. WVhen thetr'u'nnions are in the forward extremities of the grooves, the;

plane is elevated above its operating "position', and when "so'adjusted the knife is free from engagement with the floor or other surface upon which the plane stands. In

order to facilitate fthe'ma nipulation of the plane, whereby its "trunnions are moved back and forth in the grooves- 361. arms 38 are'iperforated at "their rearv extremities to These arms-; are connected. forward of the trunnions by a Below the .screw' and. located; outside of the member 27 and;

From thelrear portions of these rod 39. The forward extremities of the arms are also connected and properly spaced by a rod 40'; These arms 38 are composed of relatively 'low'parts 41. From the forward extremities of these parts 41 the arms extend upwardly, as shown at 42, and from the upper extremities of the parts 42 the arms extend forwardly, as shown at 43. The lower edges of the parts 43 are pro- 'v'ided with recesses 44 and 45 adapted to receive the axle 10 of the machine. In other words, the arms 38 are adjusted between the members6of the main frame by changing the arms ltO cause their recesses 44- or 45 to engagethe axle. When the recesses 45 engage the axle, the forward portion of the arms. is supported by the axle, and the trun'nions of the plane are in the rear extremities ofthegrooves 36.- This is accomplished by moving the arms 38 forwardly adistance equal to that between the-recesses. 44 and 45,;and during this movement the trunnions 35 move upwardly in their grooves and rest in the forward part 46 of said grooves.

1 This: machine is adapted to be operatedby hand,that is, the user of the machine,

through the medium of the tongue 9, draws the machine over the floor to be planed and scraped. When it is desired to perform the planing operation, the machine is adjusted as shown in Fig..3;--

In order that a machine of thischaracter may properlyperform its function, it is'necessary that it be weighted, and for this reason a weight 47 of suitable mass is mounted on the frame members 6 to slidably engage them. It is locked in place by means of a screw .48 which passes through the weight, its lower extremity being threaded and passing through a securing spring 49, the springbeing locked in place by a nut 50. When it is desired to lock the weight I in the adjusted position upon the frame, the SpI1I1g, Wh10l1 is bow-shaped, is so arranged that. its opposite extremities 51 engage the" under sur aces of relatively narrow rails 52 of: the frame members 6. These rails are formed b I making relatively large openings in the si" es of the said members, the rails 52 boundin thesaid'openings on their upper sides. hen theapparatus is; used for planing purposes, the' weight is adjusted to occupya position. directly above the body of the planing device (see Fig. 3). When, however, it is used for scraping purposes,

'the weight is moved farther rearwardly, as shown in Fig. 1,.where'by its downward I force is exerted on the rearextremity of theframe, and consequently upon the scraping device. .When the device is inuse either for planmgi or. seraplng purposes, the

weight-may be moved to the. extreme forward'positionfshown in Fig. 1, whereby it ,will act to elevate the rear: extremity of'the v maybe moved "forwardl dotted lines in Fig. 1.

.11am; I

The forward extremities of the grooves I i 86 are open at the upper edges of the lower rails 53.0f the frame members 6, to permit the passage of the trunnions of the plane when it is desired to remove the latter.

' The forward extremity 54 of the plane extends. below and beyond the transverse member 39 connecting the arms 38, as heretofore explained. By virtue of this construction the forward part of the plane is prevented'from moving upwardly, and the rear part from swinging downwardly farther than 1s deslrable.

that is, the part extending in the rear of the trunnions, is heavier than the partextending, forward of the same, and ifit were not for the construction just described, there would be a tendency, when the plane is not in use, for its 'rearportion to swing down Y wardly and "itsforward portion upwardly to a corresponding extent, which is undesirable. When it is desired to elevate the forward portionof the main frame to a con-' siderable' extent, the axle of the wheels 12 may be removed from its normal position,

in lower openings .55 formed in the frame.
